Specification of Letters Patent.

v Patented Feb. 4, 1908.

Application filed January 31| 1907. Serial No. 355.047.

vTo' all whom fit may concern.'

Be it known that l, THoMAs L. T OTTEN, a citizen ofthe United States,residing at Brooklyn, in the county of Kings and State the following isa s ecification.

This lnventlon re ates to a carpet sweeper which can be made practicallydust proof; and which also possesses other features and i the inventionresides in the features of construction set forth in the followingspecification and claim and illustrated in the annexed drawlng, inwhich:

Figure 1 1s a front elevatlon of a carpet sweeper embodying thisinvention. Fig. 2 is a section along the line w w Fig. 1.' Fig. 3 is asection along the line :c :l: Fig. 2. Fig. 4 is a front view of thehandle of Fig. 1 partly in section. Fig. 5 is a section along line z zFig. 4. lig. 6 1s an end elevation of the sweeper. Fig. 7 is a sectionalong y y Fig. 1.

In this drawing is shown a casing a with bottom sections b hlngedthereto at c c. The caslng has fixed fulcrum polnts e to each tof whichis fulcrumed a lever d, to each of which levers a bottom section islinked as seen atf. The levers are of the first class order andconnected at their inner ends to a stem g having a handle or fingerbutton h by which the stern g can be rotated and moved lengthwise. Thestem g has a rotative connection with the levers, and is provided with apin or projection i which passes beneath a shoulder c on the end of thecasing when the stem is depressed and rotated.

If the handle or stem is pushed in and its locking stud or projection iturned to engage shoulder or lock part c the bottom sections b by meansof 'links f and levers d fulcrumed at e will be raised to closingposition. f the stem g is turned or released from shoulder k and itsstud i, moved along or throu h releasing part shown at the shoulder theevers d are swun to dump or open the bottom so that the co lected dustwi discharge.

As the bottom sections are hinged at their outer edges they open so asto incline inward or toward the center art of the casing and thecontents or sweepings will not be thrown outward but converged toward acentral point or line to be kept to ether. .Scattering being avoided thedevlce aids 1n maintaining cleanliness.

At two fixed points at each side of the casing indicated at m arepivotedlinks 'n which ,f at their inner ends are separately ivoted at l i 0 tothe ends or engaging parts o a bail p. This link connection hassufficient play or looseness at its pivot points m o so that it allowsthe handle or stlck q to be brought to any convenient tilt for directingthe device over the floor or car et.

The bail p has a sultable prong or fork portion and the stick gis-grooved and on a ring r. 'hen the stick has been passed into lace onthe bail or fork the ring r is rotatet to engage into the eye parts s ofthe bail (Figs. 4 and 5) to lock the parts together. By rotating thering to 'enable its split part i to successively clear the fork branchesthe stick can be withdrawn.

To the casing a is fixed a plate 2. This plate 2 is cast or providedwith arms by g which the plate is attached to the vside of the l casing.This plate 2 is thus supported by its arms at a certain distance fromthe casing so i as to leave room in which to place the arms 8 supportingwheels 7. This plate with the l adjacent wall of the casing is slottedat 3 to form a loose bearing at each side for the gudgeons 3 to not onlyturn but also have pla or movement up and down. As these gudygeons carrythe brush or rotary broom 4 such broom can come to the floor aspresently seen.

shaft of a gear 5 which en ages the ear part or rings 6 of wheels 7. Tese wheeTs. 7 have rubber or like tires to get a grip on the surfaceover which they run. Said wheels 7 have their axles mounted' on carriers'or swinging arms 8 pivotally mounted on the gudgeons 3. These arms 8have a loose pivot or fulcrum connection with the plates 2 formed by pinand slot connections, the pins being shown at 9. These arms 8 as seen inFig. 2 are of U-shape so as to extend on both sides of wheels 7 and saidarms as seen in Fig. 2 support both ends of the axle of each of ,saidwheels. These arms are pivoted on gudgeons 3.

lVhen the device is set on the floor or carpet the wheels 7 touch theground and the gudgeons to sink and carry the brush to the car et orfloor.

adjuster or screw stein 10 with nut 11 arrested by a shoulder or eye onplate 2 can be made to limit the swing or drop of gudgeons 3.

shoulder of the stick sits the rotatable split Each gudgeon is keyed tothe hollow` arms 8 swing about fulcrum 9 to allow the l of gear 5 formsa feather connection.

On running the device along the rotating wheels 7 by gears 6 and 5rotate the gudgeons with the brush 4 to give a 'positive motion.

The gudgeons 3 feather in the hollow hubs of gears 5 and when thegudgeons are held back against the action or pressure of springs 12 thebrush can be withdrawn or replaced.

As the casing has practically no opening except the small slots 3allowing play of the gudgeons 3 no dust can escape. The slots throughwhich the gudgeons 3 pass do not extend through the bottom edge of theend walls of the case, but as seen in Fig.- 6, such slot is of limitedextent.4 In practice, it has been found that such slots need not be morethan three-quarters of an inch in length by three-eighths of an inch inwidth. Practically no dust can escape from the casing through such smallapertures.

The gudgeons 3 can be retracted against the action of spring 12 by a pinor peg 14 (Fig. 3) which forms a finger piece and 'which peg alsoengaging a slot in the hub When said gudgeons are released the spring 12forces these gudgeons back to engaging position.

Now what I claim is:

1. In acarpet sweeper, a bail having parallel uprights provided witheyes, a handle provided with oppositely arranged grooves in its lowerend and a shoulder near its lower extremity, said uprights adapted tofit in said grooves and said shoulder being located belowand adjacent tosaid eyes, and

' a locking ring adapted to pass through said eyes and engage saidshoulder.

2. A carpet sweeper comprising a casing provided with verticallyelongated bearings, gudgeons adapted to turn and lay in said bearings,carriers swinging on t e gudgeons and wheels on the carriers geared tothe gudgeons, said gudgeons being spring pressed or yielding toreleasably engage a brush.

3. A carpet sweeper comprising a casing having its sides provided withbearing slots of limited extent so as not to pass through the bottomedges of said casing, a rotary brush in said casing, gudgeons connectedwith the brush and extending outside the casing and adapted to turn andplay in said bearing slots, carriers swinging on the gud.

geons and wheels on the carriers geared to the gudgeons, said carriersand wheels all being outside of andfree or clear from the casing so asto leave the side wall of the casing unbroken except at said bearingslots.

4. A car et sweeper comprising a casing provided with bearing plates,said casing and plates having vertical bearing slots, a rotary brush insaid casing, gudgeons guided in the slots and detachably engaging thebrush, and springs yieldingly holding said gudgeons in engagement withthe brush.

5J A carpet sweeper comprising a casing provided with bearing plates,said casing and plates having vertical bearing slots, a rotary brush insaid casing, gudgeons guided in the slots and detachably engaging thebrush, traction wheels geared to the gudgeons, threaded stems connectedwith the gudgeons'7 eyes on said plates through which the stems looselypass, and nuts adjustable on the stems to limit the downward movement ofthe gudgeons and brush. 4

In testimony whereof I have hereunto setV `my hand in the presence oftwo subscribing witnesses.
